Cores |
Cores are preformed sand
aggregates placed in the mold to shape the interior or a part of a casting that cannot be
shaped by the pattern. |
- In the insert plate, there is no feature that has to be formed
by a core.
- But a core was used in the mold, so that two plates can be
formed in a single casting pour.
- The drawing to the right shows how a core was used to separate
and form two plates in a single mold.
